Thanks

Sent them an email about the headlights..  wonder if there might be a group by possibility here!

v nice indeed, my favourite body kit.

Two questions -

who did the dash (can we have some more photos)
what are the lights, and did you have to cut the bumper for them?

I have invested in a power bleeder, so pressurizes the reservoir to force the fluid through, also means I don't have to go anywhere near the pedal.

When you say is it piped up properly, do you mean the right connections to the right points in and out of the ABS? or do you mean the physical runs?

The runs are not the same as stock (not quiet) so there could be some highpoints causing airlocks?  Definitly no visible leaks.

Also, when the MC is isolated and blanked off its the same - no pressure.

At the moment Im thinking I have knackered both MC's (old one and a reconditioned one) by not being gentle enough during the bleed process.  But I am also not ruling out pedal travel, as its all been disconnected I wonder if something has not gone back right in the mechanism.

I guess its possible i have been too rough with both damaged them both.

I will try the third tonight and be extra careful.

I will report later on tonight.

Thanks,
James

I have a third (old) MC from a 92, probably original so I will give that a go.

If the problem is still present that could mean 3 broken MC seals, so that might make it less likley to be the MC.

Im going to try rebleeding the MC and then bleeding at each joint just incase it is air

But any other suggestions are more than welcome!

Cheers /J

Cheers - any help appreciated.

Pedal travels to a stop, then returns, can repeat over and over again with no build up of pressure, no resistance.  Pedal is not firm, and does not change after pumping.

Yea, same with standard MC. got some work to do before car will start, so not an option at the mo.  I would have thought a badly operating booster would just make the pedal much harder?

Thanks,

Engines not running, so no vacuum assist.  Can the brake booster fail to fully operate the push rod? 

Im thinking at the moment, pedal play, or push rod clearance, maybe pedal is bottoming out before MC is bottoming out?

Pedal returns back no problem.

Strange it doesn't build pressure even when the two circuits are blocked of the other connections near the MC.

It's bled multiple times and there;s no air coming out of the lines.  I bleed the KSport on the outside nipple first, then inside on the caliper.  Just curious why its the same problem even with all of the brake circuits blocked off.

Im not sure the MC is at fault as I first tried with the original MC, and thought the problem might be an undersized MC so I upgraded it to 929 anyway due to larger brakes, but fault still exists.

Reservoir is original though, can these go wrong in anyway?

Thanks!

Hi,

Obviously doing something wrong or something is faulty here:

1) Fitted KSPort front and rear
2) Replaced master cylinder with 929 for larger brakes
3) ABS unit is OK
4) Replaced all lines with copper/nickel lines
5) Bench bled master cylinder
6) Bleed brakes in correct order

No pressure build up at all can pump and pump and pump but nothing.  System does not have any visible leaks.

So, I figured I would loop the connections at the master cylinder together to see if I can build up pressure just with the pedal and cylinder, but same result.

I am using the original reservoir of the old MC, can these things develop faults? 

Thanks,
James

Apologies for the large images.. anyway, cant edit the post?
